' IMPROVEMENT 1N MAoHINEs 'POE MOULDTNG'OOTLLARS.

u tlgeftnuh trimm itin there Sitters:-4 uutxig giri ,tt time Be it known that I, GEORGE H. SPauLDINo, of orwich, in the county o fNcw London, and State of' Goin nectict, have invented anew and useful Improvement in h/Iachines` for Moulding Collars, ot`-wh ic`h the folloiing is a full,- elear, and exact descriptomreforenco'being had tothe accompanyiugdrawiugs, malripg a'. part of this specification, ini Which-w i Figure 1 representen perspective view -ofoa machine embodying `my improvement, and i Figure 2 is a vertical section of the same.' j u t' I l `The object of myfinventicn is to mould a collar to the proper shape, without puokering oxywi-inlgling the i same, and at the same time, to' hold the collar firmly in position while beingmoulded,` withoutztheI necessity#- otherwise clamping.' it atthe ends.; and the invention consists in the use or employment of al1-,img or l India rubber or othersuitabl'e elastic material, -placed within a frame or proper support and, in. combination.

'with such anelastic ring or bed, of a former which may be stationary, and 'matl'e to expand, or it may be of f tapering form', and m'adeta'mcv'o `'vertically.within the said ring or bed,'or the ring 4erber may bojmade to move within a. stationary former. Y 4 i 4 In moulding'collurs, when the prcssure-surfaces .are cfa 'hard or inelastic material, the grain or bresof the material ot'` which the collar consists are liabloto become-'displaced or disarranged, thuspresentingA an uneven surface and irregular thickness, but 4in my inventionv thefriction'of Vthe India rubber holds ther-.011er Virmly, i 3 and presses it evenly throughout its entire length;thudsncaysingt tprh'gjyenlyntretchodfendpreyenting"'the' j" fibres from being 'displaccchand insri'gan even thiol-mess, anda smooth, unbroken surface on the collar. Referring to the drawings, 'A represen-ts the frame of the machine, on the top of which'is secured a; circular block or frameB, having a central opening, and on' `its innersidea recess, in which is fitted a ring or; bed of 'India rubber or other suitable elastic m'z'tteriul, Cf 'D D representa sericsot4 bars of wood or other suitable material, arranged in a circle, and confined-within a ring',- E. I lhese bars extendfdownwards ivitbinthe frame, as shown in fig. 2. Just below their-ing E are bloclz-s or'pieces d ,'of the form showmnttuched to earth of the .bars D, and when in their normal position, are nearly in contact with .the rubber ring'C, a. suciontpppc'obeing,

loft between the'two 'for the 'in-sertonof atc'ollar. Y Within the upper porti'on'of 'the ser-ies of bars D, is a -blo'clc or ringfof India rubber, F, -yrhichf--serles` to keep the said upper portions rof the bars in place, or to retain' them in place after having beend-i'st'ende'd at their, lower ends. The inner 'ends oi .the'lowerfportions of the bars-D arclbevelled, as shown g.'2,1and rest`upon a bevellcd block er ring, G, which is set upon a baul-I.. The bar H extends downwards through a cross-piece, i I, in which it slides;fr cely,and on its lower Vend is a-rollei, It, which latter isV supported upon a orang-K, attached tothsshafts. i j,

The operation is as followsr The collar tobc inondod is 'placed bctweentho projecting portions- Hoffthe fr bars D and the India-rubber,ringV or bed C, the barsfbixig kept in a vertical position, by means of-the rubber? i", block F, arid the hevelledwlieel or block-Gr beingI also depressed'to-tho poiut`oi` coincidence withfthebeifelled ends ofthe-bars. The shaft S. being then turned, thfcanfK elevatcs the bar H and block Gpwrichilntte'r I causes the lower portion o f the bars D to disten'd or spread` apnrt, and thus press the projeeticnsicl Va'gaiiistftllo 'India-rubberlri'ngor bed C.` The collar is thus firmly held throughout its c:'itiio.1egth, andan eren pressureapplied to the entire mouldedvsurfaccof'the collar. .l i Instead of the expandinghasl), a-eoni'cal ortapcrin` blockmay'bc employcthnhieh may-be forcedup i through the opening in the elastic bed or .the said bed maybe made t more4 upon a-stationarjformeri 'Having thus described my inventiornl what.; c lainnosnei'v, and desire'to secure by Letters Patengis- Thev lc onihinatior, with 11n @Xpflig f01e,lnfltelnsticbed or cushion, C, `against whichthe collar is f:
